Description
~53~L3 FIELD OF THE INVENTION
The present invention relates to lining arrangements for receptacles such as cylindrical steel drums or barrels or other containers for liquids or particulate materials.
BACKGROUND TO THE INVENTION
Cylindrical steel drums conventionally have end walls sealingly fixed to a cylindrical side wall with flanges provided in one of the end walls receiving screw plugs s that the contents may be filled and discharged through the flanged opening. For many products a lining such as a plastic-type lining is required to protect the structure of the drum from contacting the contents. One known method of applying a suitable inert coating to the interior of such a drum is to melt a plastic coating onto the interior surfaces of the drum while rotating the drum at elevated temperature, a particulate supply of material for forming the plastic coating being first inserted into the drum.
Another approach has been to manufacture blow-moulded free-standing plastics liners which are placed inside the drum during its assembly and before the drum is shipped to the customer. Such liners, however, are expensive and a problem has existed with respect to the replacement of the liner when the drum is reconditioned. Since the liners are

For many products a lining such as a plastic-type lining is required to protect the structure of the drum from contacting the contents. One known method of applying a suitable inert coating to the interior of such a drum is to melt a plastic coating onto the interior surfaces of the drum while rotating the drum at elevated temperature, a particulate supply of material for forming the plastic coating being first inserted into the drum.
Another approach has been to manufacture blow-moulded free-standing plastics liners which are placed inside the drum during its assembly and before the drum is shipped to the customer. Such liners, however, are expensive and a problem has existed with respect to the replacement of the liner when the drum is reconditioned. Since the liners are
- 2 -:~22S3~3 blow-moulded free-standing liners, the wall thickness is relatively large and rigid and thus transportation and storage of these liners is very expensive.
With this problem in mind, it has also been proposed to manufacture a liner which, although being relatively heavy and having a substantial wall thickness, is designed to be foldable to reduce storage and transportation volume, However, such liners have creases at the folds and these creases are difficult to remove and may initiate premature failure of the liner.
The limitations of the previous proposals are such that new and useful alternatives would be desirable.

Very advantageously, two such glands are provided and interconnected with the wall porn on opposite sides -thereof, one gland being adapted to be opened to empty ingress of air within the liner whilst the contents are discharged through the other gland.
It will be appreciated that the material forming the flexible liner can be chosen to suit the intended contents and the material could be simply a film of plastics material, a single or multi-ply structure and indeed could be a laminate. One important application of the invention is to the case where the liner is of a laminate about 125 microns thick with an interior layer of highly flexible relatively inert plastics material (such as polyethylene) and a exterior layer of a relatively tough and durable material (such as nylon). For example, a polyethylene interior layer of about 100 microns may be used with advantage together with an exterior nylon layer of about 25 microns thickness.
However, many other structures may be advantageous for particular applications.
One highly effective form for the air discharge means is a screw-threaded aperture provided in the wall portion and adapted to be closed by a screw-plug having sealing engagement.
The invention can be most advantageously and economically implemented by the use of a thin walled liner and, furthermore, for a given receptacle design, a range of liners suitable or different products can readily be I
provided. Furthermore, the nature of the liner permits a compact liner to be provided for storage and transportation purposes, yet a highly effective and reliable product can be achieved. By virtue of the combination of features according to the invention an effective and economic result can be achieved, the walls of the receptacle providing structural characteristics with the liner acting as a reliable barrier. By virtue of the liner being held in substantially intimate contact over the interior walls of the receptacle, the risk of liner damage due to relative movement between it and the interior walls is minimized.
Furthermore, when it is desirable to recondition a drum it can be a relatively simple process to fit a replacement liner after the receptacle has been opened by removal of the wall portion from the body portion.

Figure 2 is an elevation Al view of the liner used in Figure 1 but shown on a reduced scale;
Figure 3 is a plan view of a gland for the liner of Figure 2 but to an enlarged scale;
- ~2~53~
Figure 4 is a cross-sectional view on the line I of Figure 3; and Figure 5 is a perspective view of a second embodiment of a receptacle with a liner therein.
DETAILED DESCRIPTION OF THE DRAWINGS
Figure 1 shows a receptacle in the form of a cylindrical steel drum (10) having installed wherein a flexible plastic liner shown in more detail in Figure 2 and secured to a top en wall tl3) of the drum by two plastic glands I shown in more details in Figures 3 and 4. The drum (10) is of conventional form and has a sheet metal side wall (12) having at each end an outwardly directed bead with which the top and bottom end walls (13 and 14) are interconnected by a sealed seam effected by rolling.
On diametrically opposite sides of the top end wall.
these are a pair of large openings (15) and small openings (`16) respectively provided by axially outwardly directed skirts having a sharp shoulder with which the glands (44) are fitted as described in more detail below. Centrally located in the top end wall (13) is a venting opening (17) pitted with a screw-threaded flange for accommodating a screw-threaded sealing plug which is not shown in the drawing. The flange has a polygonal shoulder accommodated ~2~i3~3 in a corresponding shaped interior recess in the end wall for providing torque resistance.
The liner (11) shown in detail in Figure 2 is of bag-like form and is illustrated when laid out flat and viewed in elevation, the respective sides being similar and comprising front and back panels (40,41) having respective apertures around which a respective gland (~) is attached as described below, the panels being heat sealed together along their respective edges (45). Furthermore, to facilitate discharge of liquids from the liner when installed in a drum, liquids are preventing from reaching the corners of the bag-like structure by provision of subsidiary heat seals (46) directed across the corners of the bag.
The panels (40,41) can be of any suitable material which may be plastic film (slither single ply or multi-ply structure) or if desired may be of or include laminated materials. For example, good results have bee obtained from the use of a single ply laminated sheet of about 125 microns thickness with the inner layer of the panel being polyethylene about 100 microns thick and the outer layer being about 25 microns thick and of nylon. Another useful structure is obtained by a laminate having an interior layer of polyethylene film of about 50 microns thick and the outer layer itself being a laminate about 75 microns thick. This outer layer can be a laminate structure having the layer directed towards the inner layer of the easel being of q 53~3 polyethylene and about 50 microns thick whereas the outer layer of this laminate facing the exterior of the liner being about 25 microns thick and of the nylon.
Referring now to Figures 3 and 4, each gland (44) is an injection mounded component of thermoplastic material such as polyethylene and has a pear-shaped base (51) from which a pear-shaped outwardly directed flange (50) projects so that a portion ox the panel (40 or 41) surrounding its opening may be welded to the underside of the flange (50).
An upstanding internally screw-threaded cylindrical projection (52) extends from the base (51) and has a reduced diameter the neck (53) terminating in a shoulder (55) and leaving a larger diameter head (54). This cylindrical projection can be fitted with a screw plug to close the bag and particulate or liquid material can be introduced into the bag or discharged therefrom readily.
A relatively small diameter upstanding spigot (57) also extends from the base (51) and is hollow but is integrally formed with a top cap I which provides an outwardly directed enlarged head for the spigot. The spigot (57) and the cylindrical projection (52) carry respective 0-ring seals (60 and 59) and each gland ~44) is fitted and secured to the top end wall (33) by snap-fitting respectively the projection (52) and spigot (57) through the openings (15 and 16?. The upstanding skirt defining these openings snap-fits over the head (54) of the projection (52) and over the Jo _ Lowe top cap (58) of the spigot (57) to engage tightly and establish a seal. The spigot (57) has a torque resisting function when a screw plug is inserted or removed from the cylindrical projection (52).
Figure 5 shows a second embodiment in which like parts have been given like reference numerals. the distinction of the embodiment of Figure 5 being that an alternative configuration is provided for attachment of the top end wall (66) to the side wall (65). Whereas the drum of Figure 1 is known as a "closed head drum", the drum of Figure 5 is known as an "open head drum" since the top end wall (66) is simply clamped into position, the periphery of the top end wall having a rolled over skirt which engages over a corresponding outwardly directed bead at the top end of the side wall (65): a clamping ring (67) is fitted over the assembly and tightened by means of a nut (68) and bolt (69). It is best to locate some sealing material between the faces of the end wall (66) and side wall (65) which are to contact one another.
Assembly of the combination of the receptacle with the liner in both the described embodiments is similar in that the liner (11) is secured by snap-fitting the glands (44) through the respective openings in the top end wall for the drum, the lands being located so as to be within the drum US when assembly is completed and then the top end wall with the attached liner is secured to the side wall of the drum.
_ I _ ~5~3~3 A screw-threaded plug is sealingly engaged in one of the glands and compressed air introduced through the other gland to expand the liner as generally indicated in Figures 1 and 5 by the arrows and the reference "kiwi" referring to compressed air. Figures 1 and 5 show the line just before complete expansion has occurred. Air from between the liner and the interior ox the drum wall escapes through the opening (17) as the liner is expanded and when the liner has been pressed into intimate contact with the interior walls of the drum, a closure plug is screw-threadably engaged in the opening (17) to prevent return of air.
The liner may now be filled with contents and upon subsequent discharge of the contents a partial vacuum is maintained 80 that the liner is retained in substantially intimate contact with the interior surfaces of the drum.
The invention can be applied to embodiments in which the liner it adapted to hold contents within a large range, for example 10 liters to 300 liters. The material chosen for the glands and the liner is selected to suit the material to be packaged, polyethylene being readily available, useful and relatively cheap material for many purposes but may be substituted where required to suit specific products.
With this problem in mind, it has also been proposed to manufacture a liner which, although being relatively heavy and having a substantial wall thickness, is designed to be foldable to reduce storage and transportation volume, However, such liners have creases at the folds and these creases are difficult to remove and may initiate premature failure of the liner.
The limitations of the previous proposals are such that new and useful alternatives would be desirable.
